7 Claims.

The object of my invention is to provide a means and method of handlingcontinuous form stationery with interleaved carbons, and particularlyinterleaved carbons that correspond approximately to the length of twoforms and which can be used repeatedly between successive forms.

It is the object of the invention to provide a means of positioning-suchcarbon sheets automatically between the paper sheets, so as to permit ofthe duplicate writing of messages on successive forms, using the samecarbon sheets between the successive forms.

In particular it is the object of my invention to do this in connectionwith business machines, such as typewriters and the like.

It is the object of this invention to provide an apparatus which willsupport and feed a plurality of paper strips constituting continuousform stationery around the typewriter platen, or the like, with a groupof interleaved carbon paper sheets; and after the message has beenwritten, the combined paper and carbon sheets are returned to theirinitial position before writing; and thereupon the carbon sheets areheld against forward movement temporarily while the written upon papersheets comprising one form are again moved over the platen to tear offposition and are torn off with the next succeeding set of forms, whichhave not been written upon, positioned for the new writing operationwith the carbon sheets therebetween so that the carbon sheets and thenew paper sheet forms may proceed through another writing cycle.

It is a further object to provide an attachment for a business machine,such as a typewriter,

' which will guide the paper and carbon sheets into and out of writingposition, and which will, at appropriate intervals, hold the carbonsheets from forward movement during the forward movement of the papersheets.

It is a further object to provide guides on said mechanism which serveto maintain the paper sheets with their forms in alignment.

It is a further object to provide such a mechanism that can be raisedand lowered and actuated for holding the carbon sheets or releasing themby a single movement of the operators hand.

It is an object to provide such a mechanism that is so light in weight,that it does not impede or affect the normal operation of the typewritercarriage.

Referring to the drawings:

Figure 1 is a front elevation of the mechanism in its elevated positionwithout paper or carbon;

Figure 2 is a side-elevation of the mechanism in its elevated positionon the typewriter without paper or carbon;

Figure 3 is a similar view with the mechanism in its lowered position;

Figure 4 is a side elevation thereof;

Figure 5 is a top plan view partially broken away showing theinterleaved arrangement of the paper sheets and the'carbon sheets;

Figure 6 is a section taken longitudinally through the carbon sheets andthe paper sheets showing the interleaved arrangement;

Figure 7 is a perspective of the assembly of carbon sheets andsupporting strips.

Figure 8 is a plan view of the continuous paper sheets and carbon sheetswith respect to their location to the typewriter platen at the fourdifferent stages of the operation of the apparatus and four stages ofthe method.

Referring to the drawings in detail:

I is a typewriter or other business machine having a platen 2 with aknurled hand wheel 3 for rotating the platen. 4 indicates the writingpoint while 5 designates the carriage carrying the platen, such carriagehaving the back bars 6 and I on which are mounted side frame members 8of a frame. This frame is further composed of a transverse bar 9 onwhich is mounted a guide l0. Optional members II to serve as stops mayalso be employed.

The frame just described is attached to the carriage by a latch fingerl2 pivoted at l3 on the side frame members 8. This frame consisting ofthe side frame members 8, the interconnecting cross member 9 and theguide member ID is provided with a tilting paper guide frame consistingof the side arms M which are provided on the side frame members 8 at 15.The outer ends of these side arms 14 are connected by the axle IS onwhich is mounted a paper guide roll I! and guide flanges 18. The flangesl8 are fixed t0 the axle [6 by set screws IS. The roller I'l freelyturns upon the axle IS. The lower ends of the side frame members M areprovided with levers 20 which are joined at the rear of the device by arod 20. Attached to rod 20' and arranged to slide transversely thereonas the carriage of the machine is moved, is a pitman 2| which in turn ispivoted at 22 to a one arm 23 of a bell crank lever pivotally supportedon the back of the typewriter I at 24. The other arm of the bell crank25 is pivotally connected at 26 to a pitman 21 which is pivotallyconnected at 28 to one arm 28 of a bell crank pivoted at 30 and providedwith another arm 3| having a finger piece 32. In this manner the pivotedframe l4 and associated parts are raised and lowered. The pivoted frameI4 is provided with cross guides 33 and 34.

A carbon retaining latch is provided as follows. Pivoted links 35 and 36are pivoted at their lower ends 3'! on the side frame members 8. Theirupper ends are connected at 38 to one arm of a bell crank 39. This bellcrank consists of a wire wound around the axle l6 to form a loop at 40and extending into a second arm 4| having a hook 42 on the outer end.This hook is in its retracted position when the frame members [4 and themembers 35 constituting the pivoted frame mechanism are in their loweredposition as shown in Figure 3.

The hook is advanced, however, when the frame is elevated as shown inFigure 2. The purpose of this hook, as hereinafter described is toengage the transverse carbon carrier plates to hold the carbons frommoving after a writing operation has been performed and it is desired tomove the paper sheets relative to the carbon sheets.

To this end, there are provided a plurality of superimposed paper sheetsdesignated 43a, 43b, 430, etc. It wil be understood any number of suchsheets may be employed. These sheets are divided by transverseperforations at 44 into a series of forms or tickets upon which areprinted, ordinarily, various types of business forms which are usuallyidentical.

Interleaved between the paper sheets adjacent the free ends of the papersheets are the carbon sheets 45a, 45!), etc. Each of these sheets isattached to a transverse plate carrier 46a, 46b, etc. Such a carrier isusually of light material such as paste board, etc. These carriers arepreferably attached together as by a staple 41.

The carbon sheets so carried are long enough to cover the areas of theprinted forms of two adjacent tickets but they are not as long as thetotal length of the two tickets. The carbon are in their retractedposition. Then the operator presses a finger piece 32 elevating thepivoted frame and bringing the hook 42 in advance of the carbon carrier45a, 46b, etc., preventing any forward movement of the carbon sheets.While the carbon sheets are so locked in position, she again actuatesthe platen to move the paper sheets forwardly the length of the writtenupon tickets. In so doing, the written upon tickets are moved forwardlybeyond the end of the carbon sheets which are held stationary. This iscontinued until the perforated line 44 known as the tear-off line is inposition for tearing of! the paper sheets which have been written uponand which are free from carbons. This leaves the free forward ends ofthe next adjacent set of forms or tickets in writing position with thesheets extend throughout the length of the last 1:

group of tickets which are being written upon in the typewriter and thenext to the last group of tickets which are yet to be written upon butwhich are next in order of succession for that purpose. This arrangementis shown in Figure 5 particularly.

Operation With the ends of the paper sheets in position with the top ofthe sheets just beyond the writing point 4 so that the top line of theform can be 7 written upon, the ends of the carbon sheets are locatedslightly above this writing point extending backwardly throughout thelength of the form or ticket being written upon and substantiallythroughout the length of the next succeeding ticket which will be nextwritten upon. k

As the paper sheets and carbons progress through the machine during thewriting upon the first form and the making of carbon copies through thecarbon sheets upon the underlying etc., reaches a position above thehooks 42 which 75 carbons interleaved between them. The tilting frame orside arms l4, etc., are then lowered and when this is done the hook 42is withdrawn releasing the carbon carrier so that the carbon sheets canprogress through the machine with the paper sheets for writing upon thenext set of forms on the next set of tickets.

It is understood that the paper sheets may be supplied from a zig-zagfolded pack as illustrated or from rolls or in any other way that provesto be suitable.

It will be observed that the curved upper end of the stationary guide isuseful when the pivoted, frame is lowered to cause the paper and carbonsheets to bind and stay together without slipping as they move forwardthrough the business machine. When the pivoted frame is lifted, thepaper sheets and carbon sheets, which have been backet together andwhich are to be independently moved in the opposite direction, arereleased from this binding action because these paper and carbon sheetsare lifted from the curved stationary guide.

Furthermore, with the pivoted frame elevated you cannot move the papersheets backwardly because their weight will cause them to buckle but youcan move them forwardly while the carbon sheets are being retained.

It will be understood that I desire to comprehend within my inventionsuch modifications as come within the scope of the claims and theinvention.
